Solutions to the Molar Mass Practice Worksheet:

Important note to students: All of the units given here are “grams per mole”,
which may be abbreviated as “g/mol”, “grams/mol”, or “g . mol-1”, depending on
how your teacher likes to see it written. They all mean the same thing, but it’s
probably a good idea to use whatever your teacher showed you in class. Also,
remember that if you don’t use units in your answer, the answer is wrong!

All answers are rounded to the nearest 0.1 grams.

1)    102.9 g/mol
2)    303.3 g/mol
3)    74.1 g/mol
4)    164.0 g/mol
5)    96.0 g/mol
6)    180.0 g/mol
7)    357.4 g/mol
8)    68.1 g/mol
9)    183.4 g/mol
10)   126.9 g/mol
